What condensing black prepersitation formed in fire tube boiler water scale hazardous due to the condensing boiler is located in a different region. There are differences in the water hardness. When high chloride content and sulfate in water, in the condensing boiler as the water will continue to evaporate, so that they go beyond the limits of its saturation concentration is precipitated, and the drum, adhering deposition of water wall, and gradually form hard , insoluble in water scale. Multi scale deposited within the drum and the heating surface of the water wall, causing great harm to the condensing boiler and its operation. The main harm is done to scale: (1) scale is a poor conductor, its thermal conductivity is 1/5 of steel, the scale will affect the heating surface thermal conductivity. The increased thermal resistance due to heat caused by fuel waste, reduce the thermal efficiency. (2) due to the poor thermal conductivity of scale, fuel combustion heat is not well transferred to the water by the metal surface, resulting in the metal heating surface temperature increases overheating, reducing the structural strength of metal, and causing the drum is deformed Wall table, drum kits, tube wall section is reduced, which can result in poor circulation can not even over the water and cause water wall tube burn accidents, severe cases can lead to burst pipes. (3) When people using a chemical or mechanical cleaning descaling, will cause corrosion of the metal of the inner wall injury or reduce the life of condensing boiler.

Coal-fired black prepersitation formed in fire tube boiler which can be transformed into wet coal fired boilers and benefits: on specific types of boiler, the following will be involved, for this kind of boiler coal-fired boiler, because it is not only common and popular types of boilers, and the necessity Moreover, the site is still in the product, so have the knowledge to understand, so that can achieve the proper use and rational utilization of coal-fired boilers. 1. coal-fired boiler installation is carried out according to what drawing? Which can be converted into fuel boiler it? Coal-fired boiler installation, in general, is carried out in accordance with the overall assembly drawing boiler, thus, a good job done, to avoid incorrect installation. And this kind of boiler, can be converted into fuel boiler, however, need to have some expertise, as well as some experience and technology, so as to ensure the smooth progress of conversion work and avoid problems in the conversion process. 2. Why coal-fired boilers can burn wet coal? Coal-fired boiler, which can burn coal wet reason is as follows: when the coal with water, the reaction occurs in a high temperature environment to produce hydrogen and carbon monoxide, in turn, accelerate the reaction rate, and to accelerate the burning speed. So, it can bring some benefits, it is worth combustion.

Analysis of steam black prepersitation formed in fire tube boiler down for maintenance and corrosion knowledge of what steam boiler down for maintenance and corrosion analysis after a close knowledge of steam boilers, must be maintained to prevent internal boiler corrosion. Second, short-term maintenance. Wet maintenance method employed; That is, after stopping the furnace, the furnace is filled with water and air is completely discharged. Third, long-term maintenance. Can be maintained using a dry method, i.e., a furnace rear stop released water, lower aperture open, the pot water dried, and the desiccant was placed in the lower aperture, regular replacement, and replacement can begin monthly check. Once, it can be done once every three months. However, it should be noted that all the desiccant must be removed before the boiler starts. Make an effective maintenance method first steam boiler, a steam boiler feedwater should be as close to the furnace temperature, preferably higher than 20 ℃. Second, we must regular inspection, maintenance and cleaning of the low water level cutting device. At least once a month to clean water level controller, water level wash at least once a day. Water level should be at the highest level; after washing, the water level should not be below the minimum safe level. If you do not wash clean, can be washed several times, but it must be cleaned at the highest level. Third, we must carry out regular sewage discharge operation, at least once (once per shift) per day. After the sewage, the sewage should check valves leak due to the influence of dirt; if so, it must be excluded. 4. When the boiler without maintaining close vapor pressure steam boiler space will keep the air and negative pressure is generated. Thus, when the re-ignition, the total steam valve should be opened first.

2019-7-29·Troubleshooting a Boiler That Won't Fire. A boiler has a pilot light that ignites incoming gas to the unit. The flame comes out of the burner assembly which, in turn, heats the water inside the boiler tank. If the pilot light does not light or the thermocouple that signals the pilot light to ignite is faulty, the unit will fail to heat.
